Embodiment Construction
[0025] In order to facilitate the understanding of the present application, the control mechanism, the descaling device and the heat exchange system will be more fully described below with reference to the relevant drawings. The preferred embodiments of the control mechanism, descaling device and heat exchange system are given in the accompanying drawings. However, the control mechanism, descaling device and heat exchange system can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the control mechanism, descaling device and heat exchange system more thorough and comprehensive.
[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be d...

The application relates to a control mechanism, a descaling device and a heat exchange system. The above-mentioned control mechanism is used to connect with the transmission shaft of the evaporation main body and the driving mechanism respectively. The control mechanism includes a fixed frame, a rotating shaft, an abutment wheel, a positioning column and a sensor. The fixed frame is provided with a through hole, and the fixed frame is used to connect to the evaporation body. The rotating shaft is installed in the through hole and connected with the fixed frame in rotation; the abutting wheel is sleeved on the rotating shaft and connected with the rotating shaft in rotation, the abutting wheel and the rotating shaft are set coaxially, and the abutting wheel is provided with a mounting position, which is used for the abutting wheel It is in contact with the transmission shaft; the positioning column is set at the installation position; when the positioning column rotates with the contact wheel to the position corresponding to the sensor, the sensor senses the positioning column and sends a control signal to the control end of the driving mechanism to precisely control The driving mechanism drives the transmission shaft to drive the frame to slide at the stroke length position, thereby solving the problem of poor descaling effect of the heat exchange system.
Description
technical field [0001] The present application relates to the technical field of on-line cleaning of mechanical vapor recompression technology, in particular to a control mechanism, a descaling device and a heat exchange system. Background technique [0002] The heat exchange system is widely used in the evaporation and concentration of aqueous or organic phase solutions in the light chemical industry, especially for the concentration of waste water or traditional Chinese medicine. Specifically, under normal pressure or vacuum conditions, the heat exchange system is used for continuous or intermittent, single-effect or multi-effect evaporation and concentration of wastewater or traditional Chinese medicine. The heat exchange system controls the temperature of the system and the speed of the pressure motor through PLC (Programmable Logic Controller, Programmable Logic Controller) or DCS (Distributed Control System, Distributed Control System) to maintain the evaporation balan...
